Multi-agent setups are how production-grade agent work scales. The canonical pattern is a coordinator that decomposes a task and delegates each piece to a specialist worker, then merges the results. Each agent has its own brain, its own tools, its own system prompt, which makes it easy to route cheap turns to a cheap model and premium turns to a premium one. The cost story alone is usually enough to justify going multi-agent on any non-trivial task.
